In biology, a warm-blooded animal species's one whose members maintain thermal homeostasis; that's, they keep their body temperature at a roughly constant level, regardless of the ambient temperature. This involves the ability to cool down or produce more body heat. Warm-blooded animals mainly control their body temperature by regulating their metabolic rates (for example increasing their metabolic rate as the surrounding temperature begins to decrease). Both the terms "warm-blooded" and "cold-b… (More on Homeothermic)
